Procedure
To a mixture of 1-acetylamino-5,6,7,8-tetrahydronaphthalene (1.9 g, 10 mmol) in trifluoroacetic acid (20 ml) was added: bromine (0.55 ml, 10 mmol) solved in acetic acid (5 ml). The mixture was stirred for 15 min at room-temperature. Water (50 ml) was added and the crystals were filtered. Yield 2.6 g (97%). Mp=185.2-188.6° C.
